Filed: 1946-07-05
Abstract: 631,873. Colour photography. KODAK, Ltd. July 5, 1946, No. 20205. Convention date, July 6, 1945. [Class 98 (ii)] The colour balance of colour photographic multilayer material provided with at least two silver halide emulsion layers of substantially equal sensitivity to different regions of the spectrum, inseparably coated on a single support, at least one but less than all of the layers having an excess of sensitivity over that required to produce a balanced colour image in the material, is corrected by applying over the outermost emulsion layer a filter layer absorptive of the light causing only the excess sensitivity in the one layer having excess sensitivity, the degree of absorption being so chosen as to correct colour balance and the colouring matter of the filter layer being capable of decolourisation or removal from the layer by a bath used in the normal processing of the material to colour. The material may have red-, green-, and blue-sensitive silver halide emulsion layers successively coated on a single support, with a filter layer between the blue- and green-sensitive layers. A colloid (gelatin or water-permeable cellulose ester or synthetic resin) layer coloured with colloidal silver or a removable or decolourisable dye (e.g. soluble in processing baths or bleached by a constituent thereof, for example a sulphite) is coated over the blue-sensitive emulsion layer. A precipitant (e.g. a calcium salt) removable in the processing baths may be added to this colloid layer to reduce diffusion of the dye. The material may be processed to colour by virtue of couplers in the emulsion layers or in the developer, or may be of the silver-dye bleach type. The colloid layer may contain two or more dyes. For a yellow filter, the colloid layer may contain colloidal silver, the calcium salt of 3-carboxy-4-benzeneazo-5- pyrazolone, the lead salt of 3-carboxy-4-mtolylazo - 5 - pyrazolone, or 4 : 4 - methenylbis - (1 - p - sulphophenyl - 3 - methyl - 5- pyrazolone). For a magenta filter, the layer may contain 4 : 4<SP>1</SP>-trimethine-bis-(1-p-sulphophenyl - 3 - methyl - 5 - pyrazolone) or the aluminium lake of aurintricarboxylic acid, and for a cyan filter, 4 : 4<SP>1</SP>-pentamethine-bis-(1-psulphophenyl - 3 - methyl - 5 - pyrazolone), triphenylguanidine copper phthalocyanine sulphonate, or the condensation product of thiobarbituric acid and glutaconic dialdehyde dianilide.

Patent GB-829232-A (GB)
Title: Cobalamin producing fermentation process
Inventor: SPEEDIE JOHN DOUGLAS
IPC: C12P19/42
Filed: 1957-06-27
Abstract: Cobalamins are produced in a process which comprises fermenting a suitable liquid nutrient medium with a cobalamin-producing species of the genus Propionibacterium under substantially anaerobic conditions until at least 10% of the cell growth occurring in the complete fermentation has taken place and thereafter continuing the fermentation while contacting the medium with oxygen.  Such a medium contains a source of assimilable nitrogen and carbon and a source of assimilable cobalt, e.g. the medium may contain corn-steep liquor in a concentration in the range 200-400 mg. of nitrogen/100 ml. of medium, and glucose in the range about 8-12% w./v. of medium. Specified micro-organisms are P. freudenreichii, P. shermanii, P. technicum.  Anaerobic conditions may be maintained by carrying out the fermentation under the atmosphere of a non-oxidizing gas or nitrogen.  Contact with oxygen may be effected by passing oxygen or an oxygen-containing gas, such as air, through the medium or by mechanically agitating the medium under an atmosphere of oxygen or an oxygen-containing gas.  The fermentation may be effected at 30 DEG C. and the pH maintained at about 7 by the addition of ammonia.  The process is illustrated in detail.

Title: Improvements in or relating to time delay circuits for use in connection with electric discharge tubes
IPC: H03F1/54
Filed: 1939-07-12
Abstract: 533,635. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BURDICK, R. H. July 12, 1939, No. 20350. [Class 40 (v)] A time delay circuit for use with electric discharge tubes of the grid type comprises a resistance-capacity circuit the capacity of which is automatically charged at a predetermined rate onswitching by rectified impulses or direct current on switching on the cathode and the resistance of which is utilised to apply cut-off bias to the tube during the charging period or part thereof. The grid of an indirectly heated triode V (which may be a gas filled valve) is connected to the cathode through a resistance R1 connected in series with a condenser C across a rectifier RE and the secondary winding S1 of a transformer T the primary P of which is connected to an A.C. supply. The cathode is heated by a connection to a secondary winding S2 and the value of the resistance R1 is chosen so that until the condenser C is charged the valve is biased to cut-off. The circuit may be arranged to start the tube slowly and then cut off the anode current by adding further resistances R2, R3 which, when instantaneous cut-off of the valve is required, are separated by a switch S, the resistance R3 being connected to a point on a potentiometer R4, R5 connected across the charging circuit. A cathode resistor R6 is included in the cathode leg when an impulsing circuit arrangement is required, the impulsing being obtained in the case of a gas filled tube from automatic bias obtained as a result of current flow through the valve, or an external impulsing circuit may be included instead of the switch S. It is thus possible to control the striking characteristic of valves over given time cycles and the output of multiphase grid controlled valves when used as rectifiers.

Patent GB-431296-A (GB)
Title: Improvements in and relating to injection moulding apparatus
IPC: B29C45/70
Filed: 1934-07-16
Abstract: 431,296. Injection-moulding apparatus. BRAUN AKT.-GES., F., Zerbst, Anhalt, Germany. July 16, 1934, No. 20829. Convention date, Jan. 10. [Class 87 (ii)] T h e electrically - driven injectionmoulding apparatus described in Specification 420,728 is modified to complete each cycle of operations entirely automatically once the machine has been started. Two motors F and A are employed controlled in timed relation; the motor F serving to close and open the moulds and the motor A to charge them. The motor A advances a piston 10 to deliver material through the nozzle 5 by mechanism similar to that described in Specification 420,728 and also controls a cock through the medium of a lever 7 so that the premature discharge of material through the nozzle is prevented. Both mould parts slide on guides, and the part 27, which carries the counterpart to the nozzle, moves between limiting stops in each direction and is urged in the mould-closing direction by springs. The part 26 is traversed by the motor F through a crank 29 and connecting-rod 30, and in its closing movement it first abuts the part 27 and then moves the latter against the action of the springs into contact with the nozzle. On the return movement the springs maintain the mould in closed position until the part 27 is arrested by its stop, following which the movement is arrested while the mould cools, and afterwards the continued movement of part 26 opens the mould and brings an ejecting-pin 39<a> into contact with an adjustable abutment 48 on the frame to strip the moulded article. A handle on the shaft 32 permits manual closing of the mould when necessary. On starting the motor F to close the mould parts, the rotation of the crank 29 operates a time switch 40 which (1) cuts out the motor F, (2) starts motor A to perform the charging after a predetermined time varied by setting the pointer 46 on its dial and (3) reverses motor A to retract the piston, which movement continues until a cam 25 operates contacts to open the motor circuit. Shortly afterwards a second cam 24 operates to start motor F in the reverse direction to open the mould, this movement being interrupted while the mould cools by a switch operated by cam 42, and afterwards being continued until a contact operated by the mould carriage at the end of its stroke finally cuts out the motor F, when the cycle may be recommenced. The ejection cylinder is heated by a resistance coil which is partly short-circuited towards the end of the injection operation to provide an increased heating effect.

Filed: 1960-06-15
Abstract: 972,231. Bags, making; seaming non-metallic sheet material. R. W. BARRACLOUGH Ltd. June 5, 1961 [June 15, 1960], No. 20891/60. Headings B5D and B5K. [Also in Divisions B6 and B8] A machine for forming block bottom bags from lengths of gusseted tubing 11a of semirigid material comprises means (Fig. 15) for closing an end of the tube length and means for inflating the bag so formed and for forming a block bottom thereon. The machines disclosed produce such a bag; provide a weakened opening portion therein covered by a label; fill the bag and finally seal its upper edges. The machine of the first embodiment comprises a twelve point turret (Fig. 7) rotated intermittently through twelve working stations. The turret carries twelve bag supporting mechanisms comprising three jaw members 41, 42, 45 (Figs. 15) which can be separated by acting on a buttress 45g. A length of tubing 11 is cut and fed from a continuous roll (Fig. 12, not shown; see Division B6) to a gripper at station A which then moves to B where the tubing is siezed by members 81, 82 adjacent the bottom edges which are then heated by an electric radiator 93 to welding temperature. Members 81, 82 and the heater 93 then withdraw and clamps 101, 102 advance to seal the bottom edge of the bag; clamps 101, 102 are water cooled to set the seal. As the bag reaches station C the ungripped half of the bag is drawn away by a suction pad 111 (Fig. 17), an anvil 115b is inserted into the open mouth and a punch 118 strikes the side of the bag to produce a weakened disc portion. At station D a label 120a (Fig. 20) is heat sealed over the weakened portion, a part being left unsealed to act as an opening tab (see Division B8). At station E a second suction pad 140 opens the bag and a nozzle is inserted (Figs. 21-24, not shown), the pad 140 then closing the bag and gripping the nozzle between its walls. High pressure air, nitrogen &c. issues from the nozzle to inflate the bag, a supporting platform rising to assist in producing a flat bottom. The remaining stations of the turret are concerned with the filling and closing of the final package (see Division B8). A second machine, having a number of extra turret positions, differs from the first in providing a number of stages of preheating prior to sealing the bottom of the bag. Specification 972,232 is referred to.
